Function

 
Prohexadione calcium
 
Prohexadione calcium 
Assay: 90%TC 10%WP 
CAS NO. 127277-53-6 
 
Application Range: 
Prohexadione-calcium (Pro-Ca), 
A plant growth regulator used primarily in fruit trees to suppress excessive vegetative growth and to inhibit disease incidence, is known 
to inhibit dioxygenase enzymes and to inhibit GA biosynthesis. 

The main physiological effects of Prohexadione Calcium:  
1.Shorten the stem elongation of many plants, control the section ends growth, thicken tems, shorten plant height,and prevent lodging;  
2.Promote fertility, promote lateral bud growth and rooting. Keep the leaves dark green and upright; control the flowering time, improve 
   fruit setting and ripening.  
3.It also increases the plant resistance to disease, cold and drought. Reduce the phytotoxicity caused by herbicides,and improve output. 
4.Prohexadione Calcium can significantly shorten the stems of all rice cultivars height, and promote grain growth, improve the yield of rice grains. 

Low dosage of Prohexadione Calcium has significant performance of lodging and dwarfing on  rice, barley, wheat, Japanese 
carpet grass, ryegrass, etc. 
Also it has significant growth inhibition activity on cotton, sugar beet,cucumber, chrysanthemum, cabbage, carnation, soybeans, 
oranges, and apples,etc.
